I have made some good progress with the Sons of Horus First Company! I have now finished getting the first 19 Justaerin up to the same standard as I showed in my painting guide.
This was also the very army I took to the Bunnies Christmas get together, the only other model that was in the army was Kaelo's Horus. They were split into 2 squads and both entered play via deep Strike in between 3 of the loyal legions! They preformed well however 3 legions of fire power equals them all dead in 2 turns!
They were great fun to play and deep striking was cool! However given how much fire they took, I am considering seeing if I can get them something to ride in. Spartans would be my preferred delivery method, however they can't take them as dedicated transports and I don't have enough heavy support space available. As I really want to run them as 10 man squads my options are limited to vehicles that fit in the fast attack or Lord of War, Storm Eagles, Thunderhawk, Storm Bird or Mastadon. For the time being I will keep going with the deep strike plan and see if they take less fire with the rest of the army around!
